BOOL CMyDialog::OnEraseBkgnd(CDC* pDC) 
{
HBITMAP hBmp = (HBITMAP)LoadImage(AfxGetInstanceHandle(),"C:\\background.bmp",IMAGE_BITMAP,0,0,LR_LOADFROMFILE);
HDC hMemDC = CreateCompatibleDC(pDC->m_hDC);
CBitmap bmp();
bmp.Attach(hBmp);
BITMAP bm;
bmp.GetBitmap(&bm);
SelectObject(hMemDC,hBmp);
CRect rc;
GetClientRect(rc);
StretchBlt(pDC->m_hDC,0,0,rc.Width(),rc.Height(),hMemDC,0,0,bm.bmWidth,bm.bmHeight,SRCCOPY);
bmp.DeleteObject();
return TRUE;
}
